Document Summary
Chemical industry is a safe place to work safer than soft drink manufacturing, all manufacturing, Msds --> don"t only rely on msds for process safety info. Msds usually has some basic info, but you must supplement the msds especially for chemical reactivity. -see for example, noaa chemical reactivity worksheet and ccps reactivity management tool. Msdss can provide chemical hazard info, but not process hazard safety info. What is a proces hazard? personal hazard? process hazard: intrinsic properties of materials and processes that can either directly or through release of energy lead to harmful effects such as serious injuries, property damage, business loss, or environmental harm. Dust (can cause explosion) deflagration is form of combustion (think action movie explosions, produces fire and heat) gasoline liq doesn"t easily ignite, but vapor does if dust contacts air and heat, can deflagrate. Assessing toxicity hazards foxus on acute toxicity (vs cronic - safety)
